Best donuts in Syracuse

I'm visiting Syracuse for the first time in years. What are the best places for donuts and half moons? Also what pizza places are recommend? And another pizza related question. When I was a kid there was a place, I believe it was called the Fisheria, and they made something called Luna. It was basically a pizza with a second dough laid across the top and then cut into slices. Kinda a calzone, but open on the sides. I never knew if this was a Syracuse thing or just specific to this one place. Does anyone know if anything like that exists anymore?
